Used as a key intermediate in the synthesis of fungicides, particularly in the production of agricultural chemicals targeting fungal pathogens in crops. It exhibits strong activity in controlling diseases such as powdery mildew and gray mold when incorporated into formulated crop protection products. Its hydroxyamidine structure enhances binding to metal ions in fungal enzymes, disrupting essential metabolic pathways. Commonly applied in systemic fungicide formulations due to its ability to penetrate plant tissues and provide long-lasting protection. Also investigated for use in combination therapies to manage resistance development in pathogen populations.
